Detecting and characterising exoplanet atmospheres remains challenging because atmospheric signals can be comparable to residual noise and instrumental/astrophysical systematics. Spectral features span from a few ppm for small planets up […]
Editor’s note: according to NASA: “With its all-sky survey of the position, brightness and motion of over one billion stars in our Milky Way galaxy, Gaia will provide a large […]
There’s so little we know about circumbinary planets – planets that orbit two stars instead of one – that they can feel like the stuff of fantasy.
The T16 project has produced a uniformly detrended and systematics-corrected set of 83,717,159 TESS Cycle 1 full-frame image light curves for stars observed by TESS in its primary mission down […]
Solar analogs, stars that closely match the fundamental properties of the Sun, provide key benchmarks for testing stellar structure and evolution across different ages and activity levels.
Astronomers estimate there is at least one planet for every star in our galaxy. Called exoplanets, they orbit stars outside our solar system. But new research from McMaster University reveals […]
We present detailed asteroseismic modelling of 95 main-sequence solar-like stars and Kepler exoplanet host stars using the FICO procedure, a three-step method that combines forward and inverse techniques that enables […]
Astronomers now estimate there is at least one planet for every star in our galaxy. These worlds, called exoplanets, are planets that orbit stars outside our solar system. But new […]
The Solar Neighborhood is dominated by stars smaller, colder, and fainter than the Sun: the M dwarfs.
A new study of infant stars in the Perseus and Orion star-forming regions suggests that most close pairs of stars are born as twins in the same disk, rather than […]
